 - **2026-10-13 Docker auth documentation #37 merged (PR #38, main `eaeb4fe2`, docs `2bb2557`).** Runbook/CLAUDE/compose comment now match existing dashboard LDAP login and secrets-selected API-key mode; pepper must remain stable across recreation. Corrected Production reflection claim. Effective Compose values unchanged; independent review and diff check clear. #37 closed. #30 candidate Release publish/image prepared at code `9f711c1`, but isolated metadata smoke blocked by unresponsive local Docker; existing service not replaced, candidate cleanup remains unconfirmed. No unrelated services or daemon restarted.
 
 - **2026-10-13 #30 local Docker rollout verified.** After Docker recovered, isolated candidate passed missing/existing metadata controls; candidate keys all retired and container removed. Normal Compose rolled code `9f711c1` image `sha256:8cc430d7…` into the local Gateway with matching server/SDK artifact hashes, unchanged effective environment and ApiKey auth, preserved data volume, retained rollback image and restricted stopped-service data backup. Live GetTagMetadata: nonexistent absent479ms, SysTimeSec present77ms; health200. Deployed test key independently verified revoked. #30 closed for this local deployment; no wonder-host rollout/remote execution. #29/#27 and OtOpcUa #694/#700 remain open.
